What Makes ioSENTRIX a Smarter Cybersecurity Partner?

Project Scoping & Setting Expectations

What our competitors do

Competitors offer generic reports that overlook critical business risks and underscope projects to fit budgets, leaving customers with a false sense of security and inadequate coverage for their unique needs.

What we do

We take a clear, business-aligned approach to project scoping. ioSENTRIX ensures that your security needs are met within budget, offering transparent scoping based on your goals and resources. Our cybersecurity experts tailor projects to align with your workflows, prioritizing critical vulnerabilities for maximum value and sustainable security.

Testing Methods & Procedure

What our competitors do

Competitors rely on basic compliance testing, using automated tools and canned cases, overlooking long-term security risks and missing critical vulnerabilities. This limited approach leaves organizations exposed, without comprehensive insights for lasting protection.

What we do

At ioSENTRIX, our testing methods go beyond the surface. ioSENTRIX uncovers complex business logic vulnerabilities through in-depth application demos and abuse case creation. This hacker’s perspective approach finds the logic flaws that automated scanners and checklist testing miss, offering deeper insights and stronger protection.

Technical Findings and Reporting

What our competitors do

What we do

ioSENTRIX links vulnerabilities to business risks. ioSENTRIX aligns vulnerabilities with financial, reputational, and operational risks, helping prioritize remediation. Our reports provide actionable guidance, ensuring security efforts align with business objectives for informed decision-making and long-term protection.

Post-Assessment Support

What our competitors do

Competitors often deliver reports with no guidance on remediation, leaving businesses to manage vulnerabilities on their own. Without expert support, companies risk security gaps and struggle to implement necessary improvements.

What we do

End-to-End Remediation Support. ioSENTRIX offers continuous support, working closely with your team to provide clear remediation strategies and help integrate stronger security controls that align with your business processes.

AppSec vs DevSecOps

What our competitors do

While DevSecOps automates security in CI/CD pipelines, competitors often neglect AppSec essentials like Design Reviews and Threat Modeling. This narrow focus misses foundational policies needed for robust, business-aligned security frameworks.

What we do

We go beyond DevSecOps by integrating critical Application Security (AppSec) practices like Design Reviews, Threat Modeling, and Data Handling Standards. Our approach combines automation with AppSec to embed security throughout the software lifecycle. This ensures robust defense against business risks and compliance challenges.

Enterprise-Grade Security Planning

What our competitors do

Transactional security partners prioritize quick, low-cost fixes, neglecting broader risks and long-term resilience. This short-term approach builds security debt, leaving businesses vulnerable to risks that could have been mitigated with strategic planning.

What we do

At ioSENTRIX, we specialize in enterprise-grade security.
ioSENTRIX aligns security services with your company’s risk profile, offering strategic guidance, training, and fully managed cybersecurity solutions. Our long-term approach reduces security debt with comprehensive roadmaps to enhance your security posture over time.

Hospitality Industry – Penetration Testing

A prominent hotel chain in the U.S. partnered with ioSENTRIX to conduct a penetration test on their newly implemented room automation system, which allowed guests to control room functions via an Android tablet. The technology, while innovative, introduced security vulnerabilities that posed a risk to guest safety and the hotel’s management systems. ioSENTRIX performed a comprehensive pentest, identifying critical weaknesses in network segmentation and password policies. The remediation strategies provided by ioSENTRIX ensured that the room automation system was secure, protecting the hotel’s reputation and safeguarding their financial systems from unauthorized access.

Communication-Based Train Control (CBTC) Pentest

ioSENTRIX partnered with a passenger rail provider to assess the security of their Communication-Based Train Control (CBTC) system, which had been operational for several years. A successful cyberattack on the system could result in major downtime, financial losses, and passenger safety risks. Through a comprehensive penetration test, ioSENTRIX identified several vulnerabilities in the segmented network and proprietary software used within the CBTC system. These insights allowed the rail provider to implement critical security controls, enhance their incident response plan, and better protect their infrastructure from potential future cyberattacks.

FAQ

Frequently asked questions

What does ioSENTRIX do?

ioSENTRIX is an offensive security firm, founded in 2017 and based in Herndon, Virginia. We provide penetration testing, penetration testing as a service (PTaaS), application security, red teaming, AI and LLM security testing, continuous threat exposure management (CTEM) and vCISO services. Testing is done by hand by certified engineers at a CREST-accredited firm.

What is the difference between a penetration test and a vulnerability scan?

A vulnerability scan is automated and lists known weaknesses, often with false positives. A penetration test is carried out by people who exploit and chain weaknesses, including business logic flaws that scanners cannot see, and prove the impact with evidence. Every ioSENTRIX penetration test includes a free retest of your fixes.

Do SOC 2, ISO 27001 and PCI DSS require a penetration test?

PCI DSS v4.0.1 Requirement 11.4 requires internal and external penetration testing at least once every 12 months and after significant changes. SOC 2 and ISO/IEC 27001 do not name penetration testing as a mandatory control, but auditors and customers often ask for one as evidence. Read SOC 2 penetration testing requirements.

What is penetration testing as a service (PTaaS)?

PTaaS delivers penetration testing on a platform rather than as a one-off project. Findings appear as testing progresses, sync to JIRA, and retests run in the same place, so it suits teams that ship and test often. See PTaaS from ioSENTRIX.

Do you test AI and LLM applications?

Yes. We test chatbots, retrieval-augmented generation (RAG) systems and AI agents for prompt injection, data leakage and excessive agency, with findings mapped to the OWASP Top 10 for LLM Applications 2025 and MITRE ATLAS. See AI penetration testing and AI red teaming.

Do you offer red teaming, including physical testing?

Yes. A red team exercise pursues an objective you agree with us, starting from phishing, exposed services or an assumed breach and, when it is in scope, physical entry such as tailgating, badge cloning and rogue network devices. We record what your security team detects at each step and map every technique to MITRE ATT&CK.

How long does an engagement take, and how is it priced?

Most penetration tests run days to weeks, depending on scope. A typical web application penetration test takes 1–2 weeks, and a red team exercise 4–6 weeks. We reply in under an hour during US business hours, and after a short scoping call you receive a timeline and a fixed quote. You can buy a single test, use PTaaS, or include testing in a subscription.

Which industries and compliance frameworks do you work with?

We work with banking and fintech, healthcare, SaaS and technology, e-commerce and retail, energy, and gaming companies. Results are mapped to the frameworks you report against, including SOC 2, ISO/IEC 27001, PCI DSS and HIPAA.

Can we share the report with customers and auditors?

Yes. The report summarizes scope, method and results for executives and auditors, and gives engineers the technical detail and fix for each finding. It comes from a CREST-accredited firm that is ISO/IEC 27001 certified.
